DETAILED DESCRIPTION

Example methods and systems for social network analysis are described. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of example embodiments. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.

In an example embodiment, user interaction data of a time period for a plurality of users in a social network may be accessed. Network analysis may be performed on the user interaction data. A necktie-shaped graph may be generated from the user interaction data in accordance with the performing of the network analysis. The necktie-shaped graph may be utilized for analysis of the social network.

In an example embodiment, a strongly connected component value, an in-component value, an out-component value, a disconnected component value, a tendril value, and a tube value of a social network for a time period may be accessed. A social strength of the social network for the time period may be calculated by combining the strongly connected component value, the in-component value, the out-component value, the disconnected component value, the tendril value, and the tube value. The social strength of the social network for the time period may be utilized for analysis of the social network. The strongly connected component value may have a greatest weight and the disconnected component value may have the lowest weight in the combining.

In an example embodiment, a strongly connected component value, an in-component value, an out-component value, a disconnected component value, a tendril value, and a tube value of a social network for a time period may be accessed. A social strength of the social network for the time period may be calculated by combining the strongly connected component value, the in-component value, the out-component value, the disconnected component value, the tendril value, and the tube value. One or more users associated with the strongly connected component may be identified. The strongly connected component value may be a value of the strongly connected component for the time period. An aspect of the social network associated with the one or more users may be modified. The strongly connected component value, the in-component value, the out-component value, the disconnected component value, the tendril value, and the tube value of the social network for an additional time period may be accessed. The additional time period may be after the modifying of the aspect. The social strength of the social network for the additional time period may be calculated by combining the strongly connected component value, the in-component value, the out-component value, the disconnected component value, the tendril value, and the tube value. The social strength of the social network for the time period and the additional time period may be utilized for analysis in accordance with the modifying of the aspect of the social network.

In an example embodiment, user interaction data associated for a plurality of users for a time period in a social network may be accessed. Network analysis may be performed on the user interaction data. A plurality of example users within the social network may be selected. Each of the example users may be associated with reputation information. A motif may be generated for the plurality of example users for the time period in accordance with the performing of the network analysis. A node of the motif may be associated with a particular example user of the example users. The motif may define an expected relationship between the plurality of example users in the social network. The node of the plurality of example users may be distinguished in accordance with the reputation information of a respective example user. The motif with a plurality of distinguished nodes may be utilized for analysis of the social network.

In an example embodiment, reputation information associated with a plurality of initiating users and a plurality of responding users in a social network for a time period may be accessed. Interaction frequency data associated with the plurality of initiating users and the plurality of responding users for the time period may be accessed. An aggregated correlation between the plurality of initiating users and the plurality of responding users may be plotted in accordance with the reputation information. The plotting of the aggregated correlation may be differentiated in accordance with the interaction frequency data. The differentiated plotting of the aggregated correlation may be utilized.

FIG. 1 illustrates an example system 100 in which a community of users may use a number of client machines 102.1-102.n to be involved in a social network. The client machine 102 may be a computing system, mobile phone, a personal digital assistant (PDA), a gaming unit, a portable computing unit, and the like. The social network may be a social commerce network over with the users operating the machines may be involved in commercial exchange (e.g., buying or selling). However, other types of social networks (e.g., informational social networks) may also be used.

In an example embodiment, the social network may be a social structure made of nodes (e.g., individuals or organizations) that are tied by one or more specific types of interdependency including, by way of example, values, visions, idea, commerce, friends, kinship, dislike, conflict, web links, sexual relations, disease transmission, or airline routes. For example, a social commerce network may be a network that includes a commercial interdependency.

The client machines 102.1-102.n may participate in the social network by communicating over a provider network 104 with a network analyzer 106. The provider network 104 may be a Global System for Mobile Communications (GSM) network, an Internet Protocol (IP) network, a Wireless Application Protocol (WAP) network, a WiFi network, or a IEEE 802.11 standards network as well as various combinations thereof.

Example users within the social network are selected at block 1906. The example users may be associated with reputation information (e.g., user feedback).

A motif for the example users for the time period is generated in accordance with the performing of the network analysis at block 1908. A node of the motif may be associated with an example user. The motif may define an expected relationship between a number of example users in the social network. For example, a four node motif may be generated.

The node of the example users may be distinguished in accordance with the reputation information of a respective example user at block 1910. For example, the node of the example users may be colored in accordance with the reputation information.

At decision block 1912, a determination may be made whether to apply a texture to the motif. If a determination is made to apply a texture, additional user data may be accessed at block 1914 and the texture may be applied to one or more connected lines of the motif in accordance with the additional user data at block 1916. For example, the additional user data may include interaction frequency data and/or transaction financial data associated with the users. If a determination is made not to apply the texture at decision block 1912 or upon completion of the operations at block 1916, the method 1900 may proceed to the block 1918.

The motif with the distinguished nodes may be utilized for analysis of the social network at block 1918. For example, the motif with the distinguished nodes may be provided for presentation.

FIG. 20 illustrates a method 2000 for motif utilization according to an example embodiment. The method 2000 may be performed at block 1918 or otherwise performed.

The method 2000 may be performed at block 1918 or otherwise performed. A template including the motif and a number of additional motifs is analyzed at block 2002.

A decision regarding the social network is made in accordance with the analyzing of the template at block 2004. At block 2006, at least one aspect of the social network is altered in accordance with the making of the decision.

FIG. 21 is a block diagram of example motif display 2100 according to an example embodiment. The motif display 2100 is an example representation of four node motifs from two categories of a social network. However, motifs may be made for other categories of the social network or the entire social network. Motifs containing a different number of nodes may also be used.

The motif display 2100 includes a number of motifs 2126-2144 for a first category 2102 and a number of motifs 2146 for a second category 2164.

A distinguishing legend 2106 may include a series of distinguishing levels 2180-2124 that reflect different reputation information associated with users of the motifs 2126-2164. For example, the nodes of the motif 2126 includes a first node with a distinguishing level 2118, a second node with a distinguishing level 2120, a third node with a distinguishing level 2122, and a fourth node with a distinguishing level 2124.

Differentiated Plotting

FIG. 22 illustrates a method 2200 for differentiated plotting analysis according to an example embodiment. The method 2200 may be performed by the network analyzer 106 (see FIG. 1) in the system 100 or another system.

Reputation information associated with a number of initiating users and a number of responding users in a social network for a time period is accessed at block 2202.

Interaction frequency data associated with the initiating users and the responding users for the time period is accessed at block 2204. An aggregated correlation between the initiating users and the responding users is plotted in accordance with the reputation information at block 2206.

The plotting of the aggregated correlation is differentiated in accordance with the interaction frequency data at block 2208. The differentiated plotting of the aggregated correlation is utilized at block 2210. For example, the differentiated plotting of the aggregated correlation may be provided for presentation.

In an example embodiment, the differentiated plotting may be used to determine users' tendency to interact with others with respect of their reputation information (e.g., feedback scores). For example, the differentiated plotting may help identify whether users with high reputation information (e.g., high feedback scores) tend to interact with other users that also have high reputation information. Assortative mixing may be used to show the extent to which nodes (e.g., users) connect preferentially to other nodes with similar characteristics.

FIG. 23 illustrates a method 2300 for differentiated plotting utilization according to an example embodiment. The method 2300 may be performed at block 2210 or otherwise performed.

Reputation information associated with assorted initiating users and a assorted responding users in a social network for an additional time period is accessed at block 2302.

At block 2304, interaction frequency data associated with the assorted initiating users and the assorted responding users for the additional time period is accessed.

The plotting of the aggregated correlation of the additional time period is differentiated in accordance with the interaction frequency data at block 2206.

The aggregated correlation between the assorted initiating users and the assorted initiating users is plotted in accordance with the reputation information at block 2308.

The differentiated plotting of the aggregated correlation for the time period and the additional time period is used for the analysis of the social network at block 2310.

FIGS. 24-26 are diagrams of example differentiated plottings 2400, 2500, 2600. The differentiated plottings 2400, 2500, 2600 are example representations of differentiated plottings that may be plotted in accordance with the method 2200 and/or the method 2300. However, other representations of the differentiated plottings may also be used.

The differentiated plottings 2400, 2500, 2600 plot the aggregated correlation between initiating users' reputation information (e.g., sellers' feedback scores) and receiving users' reputation information (e.g., buyers' feedback scores).

The x axis of the differentiated plottings 2400, 2500, 2600 denotes users' reputation information, and the y axis denotes receiving users reputation information. The axes of the differentiated plottings 2400, 2500, 2600 may be logarithmically binned.

The differentiation on the differentiated plottings 2400, 2500, 2600 based on interaction frequency data may be color. For example, a score of zero to two hundred is reflected by a dark blue color, a score of two hundred to four hundred is reflect by a medium blue color, a score of four hundred to six hundred is reflected by a light blue color, a score of six hundred to eight hundred is reflected by a blue/green color, a score of eight hundred to one thousand is reflected by a green/yellow color, a score of one thousand to one thousand two hundred is reflect by a yellow/orange color, a score of one thousand two hundred to one thousand four hundred is reflect by an orange/red color, and one thousand four hundred is reflected by a red color. The colors in the legend are shown in the differentiated plottings 2400, 2500, 2600 as being gradient. However other types of representations of the differentiation may be used.

The color of each block of the differentiated plottings 2400, 2500, 2600 may be determined by the number of interactions (e.g., transactions) that happed between pairs of users with corresponding reputation information.

The differentiated plotting 2400 may represent a number of transactions of a particular category (e.g., crafts) in which most interactions (e.g., transactions) are between initiating users (e.g., buyers) that have a feedback score between twenty and five hundred and responding users (e.g., sellers) that have a feedback score between ten and ninety.

The differentiated plotting 2500 may represent a number of transactions of a particular category in which most interactions are between initiating users that have a feedback score between sixteen and sixty and responding users that have a feedback score between one hundred fifty and two seven hundred.

The differentiated plotting 2600 may represent a number of transactions of a particular category (e.g., collectables) in which most interactions are between initiating users that have a feedback score between ten and seventy and responding users that have a feedback score between one hundred and three thousand.

Platform

FIG. 27 is a network diagram depicting a client-server system 2700, within which one example embodiment may be deployed. By way of example, a network 2704 may include the functionality of the provider network 104, the network analyzer 106 may be deployed within an application server 2718, and the client machines 102.1-102.n may include the functionality of a client machine 2710 or a client machine 2712. The system 100 may also be deployed in other systems.

A networked system 2702, in the example forms of a network-based marketplace or publication system, provides server-side functionality, via a network 2704 (e.g., the Internet or Wide Area Network (WAN)) to one or more clients. FIG. 27 illustrates, for example, a web client 2706 (e.g., a browser, such as the Internet Explorer browser developed by Microsoft Corporation of Redmond, Wash. State), and a programmatic client 2708 executing on respective client machines 2710 and 2712.

An Application Program Interface (API) server 2714 and a web server 2716 are coupled to, and provide programmatic and web interfaces respectively to, one or more application servers 2718. The application servers 2718 host one or more marketplace applications 2720 and authentication providers 2722. The application servers 2718 are, in turn, shown to be coupled to one or more databases servers 2724 that facilitate access to one or more databases 2726.

The marketplace applications 2720 may provide a number of marketplace functions and services to users that access the networked system 2702. The authentication providers 2722 may likewise provide a number of payment services and functions to users. The authentication providers 2722 may allow users to accumulate value (e.g., in a commercial currency, such as the U.S. dollar, or a proprietary currency, such as “points”) in accounts, and then later to redeem the accumulated value for products (e.g., goods or services) that are made available via the marketplace applications 2720. While the marketplace and authentication providers 2720 and 2722 are shown in FIG. 27 to both form part of the networked system 2702, in alternative embodiments the authentication providers 2722 may form part of a payment service that is separate and distinct from the networked system 2702.

Further, while the system 2700 shown in FIG. 27 employs a client-server architecture, the present invention is of course not limited to such an architecture, and could equally well find application in a distributed, or peer-to-peer, architecture system, for example. The various marketplace and authentication providers 2720 and 2722 could also be implemented as standalone software programs, which need not have networking capabilities.

The web client 2706 accesses the various marketplace and authentication providers 2720 and 2722 via the web interface supported by the web server 2716. Similarly, the programmatic client 2708 accesses the various services and functions provided by the marketplace and authentication providers 2720 and 2722 via the programmatic interface provided by the API server 2714. The programmatic client 2708 may, for example, be a seller application (e.g., the TurboLister™ application developed by eBay Inc., of San Jose, Calif.) to enable sellers to author and manage listings on the networked system 2702 in an off-line manner, and to perform batch-mode communications between the programmatic client 2708 and the networked system 2702.

FIG. 27 also illustrates a third party application 2728, executing on a third party server machine 2730, as having programmatic access to the networked system 2702 via the programmatic interface provided by the API server 2714. For example, the third party application 2728 may, utilizing information retrieved from the networked system 2702, support one or more features or functions on a website hosted by the third party. The third party may, for example, provide one or more promotional, marketplace or payment functions that are supported by the relevant applications of the networked system 2702.

FIG. 28 is a block diagram illustrating multiple applications 2720 and 2722 that, in one example embodiment, are provided as part of the networked system 2702 (see FIG. 27). The applications 2720 may be hosted on dedicated or shared server machines (not shown) that are communicatively coupled to enable communications between server machines. The applications themselves are communicatively coupled (e.g., via appropriate interfaces) to each other and to various data sources, so as to allow information to be passed between the applications or so as to allow the applications to share and access common data. The applications may furthermore access one or more databases 2726 via the database servers 2724.

The networked system 2702 may provide a number of publishing, listing and price-setting mechanisms whereby a seller may list (or publish information concerning) goods or services for sale, a buyer can express interest in or indicate a desire to purchase such goods or services, and a price can be set for a transaction pertaining to the goods or services. To this end, the marketplace applications 2720 are shown to include at least one publication application 1110 and one or more auction applications 2802 which support auction-format listing and price setting mechanisms (e.g., English, Dutch, Vickrey, Chinese, Double, Reverse auctions etc.). The various auction applications 2802 may also provide a number of features in support of such auction-format listings, such as a reserve price feature whereby a seller may specify a reserve price in connection with a listing and a proxy-bidding feature whereby a bidder may invoke automated proxy bidding.

A number of fixed-price applications 2804 support fixed-price listing formats (e.g., the traditional classified advertisement-type listing or a catalogue listing) and buyout-type listings. Specifically, buyout-type listings (e.g., including the Buy-It-Now (BIN) technology developed by eBay Inc., of San Jose, Calif.) may be offered in conjunction with auction-format listings, and allow a buyer to purchase goods or services, which are also being offered for sale via an auction, for a fixed-price that is typically higher than the starting price of the auction.

Store applications 2806 allow a seller to group listings within a “virtual” store, which may be branded and otherwise personalized by and for the seller. Such a virtual store may also offer promotions, incentives and features that are specific and personalized to a relevant seller.

Reputation applications 2808 allow users that transact, utilizing the networked system 2702, to establish, build and maintain reputations, which may be made available and published to potential trading partners. Consider that where, for example, the networked system 2702 supports person-to-person trading, users may otherwise have no history or other reference information whereby the trustworthiness and credibility of potential trading partners may be assessed. The reputation applications 2808 allow a user, for example through feedback provided by other transaction partners, to establish a reputation within the networked system 2702 over time. Other potential trading partners may then reference such a reputation for the purposes of assessing credibility and trustworthiness.

Personalization applications 2810 allow users of the networked system 2702 to personalize various aspects of their interactions with the networked system 2702. For example a user may, utilizing an appropriate personalization application 2810, create a personalized reference page at which information regarding transactions to which the user is (or has been) a party may be viewed. Further, a personalization application 2810 may enable a user to personalize listings and other aspects of their interactions with the networked system 2702 and other parties.

The networked system 2702 may support a number of marketplaces that are customized, for example, for specific geographic regions. A version of the networked system 2702 may be customized for the United Kingdom, whereas another version of the networked system 2702 may be customized for the United States. Each of these versions may operate as an independent marketplace, or may be customized (or internationalized and/or localized) presentations of a common underlying marketplace. The networked system 2702 may accordingly include a number of internationalization applications 2812 that customize information (and/or the presentation of information) by the networked system 2702 according to predetermined criteria (e.g., geographic, demographic or marketplace criteria). For example, the internationalization applications 2812 may be used to support the customization of information for a number of regional websites that are operated by the networked system 2702 and that are accessible via respective web servers 2716.

Navigation of the networked system 2702 may be facilitated by one or more navigation applications 2814. For example, a search application (as an example of a navigation application) may enable key word searches of listings published via the networked system 2702. A browse application may allow users to browse various category, catalogue, or system inventory structures according to which listings may be classified within the networked system 2702. Various other navigation applications may be provided to supplement the search and browsing applications.

In order to make listings available via the networked system 2702 as visually informing and attractive as possible, the marketplace applications 2720 may include one or more imaging applications 2816 utilizing which users may upload images for inclusion within listings. An imaging application 2816 also operates to incorporate images within viewed listings. The imaging applications 2816 may also support one or more promotional features, such as image galleries that are presented to potential buyers. For example, sellers may pay an additional fee to have an image included within a gallery of images for promoted items.

Listing creation applications 2818 allow sellers conveniently to author listings pertaining to goods or services that they wish to transact via the networked system 2702, and listing management applications 2820 allow sellers to manage such listings. Specifically, where a particular seller has authored and/or published a large number of listings, the management of such listings may present a challenge. The listing management applications 2820 provide a number of features (e.g., auto-relisting, inventory level monitors, etc.) to assist the seller in managing such listings. One or more post-listing management applications 2822 also assist sellers with a number of activities that typically occur post-listing. For example, upon completion of an auction facilitated by one or more auction applications 2802, a seller may wish to leave feedback regarding a particular buyer. To this end, a post-listing management application 2822 may provide an interface to one or more reputation applications 2808, so as to allow the seller conveniently to provide feedback regarding multiple buyers to the reputation applications 2808.

Dispute resolution applications 2824 provide mechanisms whereby disputes arising between transacting parties may be resolved. For example, the dispute resolution applications 2824 may provide guided procedures whereby the parties are guided through a number of steps in an attempt to settle a dispute. In the event that the dispute cannot be settled via the guided procedures, the dispute may be escalated to a merchant mediator or arbitrator.

A number of fraud prevention applications 2826 implement fraud detection and prevention mechanisms to reduce the occurrence of fraud within the networked system 2702.

Messaging applications 2828 are responsible for the generation and delivery of messages to users of the networked system 2702, such messages for example advising users regarding the status of listings at the networked system 2702 (e.g., providing “outbid” notices to bidders during an auction process or to provide promotional and merchandising information to users). Respective messaging applications 2828 may utilize any one have a number of message delivery networks and platforms to deliver messages to users. For example, messaging applications 2828 may deliver electronic mail (e-mail), instant message (IM), Short Message Service (SMS), text, facsimile, or voice (e.g., Voice over IP (VoIP)) messages via the wired (e.g., the Internet), Plain Old Telephone Service (POTS), or wireless (e.g., mobile, cellular, WiFi, WiMAX) networks.

Merchandising applications 2830 support various merchandising functions that are made available to sellers to enable sellers to increase sales via the networked system 2702. The merchandising applications 2830 also operate the various merchandising features that may be invoked by sellers, and may monitor and track the success of merchandising strategies employed by sellers.

The networked system 2702 itself, or one or more parties that transact via the networked system 2702, may operate loyalty programs that are supported by one or more loyalty/promotions applications 2832. For example, a buyer may earn loyalty or promotions points for each transaction established and/or concluded with a particular seller, and may be offered a reward for which accumulated loyalty points can be redeemed.

A network analyzer application 2834 may analyze the social network amount a number of users of the system 100.

FIG. 29 shows a diagrammatic representation of machine in the example form of a computer system 2900 within which a set of instructions may be executed causing the machine to perform any one or more of the methods, processes, operations, or methodologies discussed herein.

The example computer system 2900 includes a processor 2902 (e.g., a central processing unit (CPU) a graphics processing unit (GPU) or both), a main memory 2904 and a static memory 2906, which communicate with each other via a bus 2908. The computer system 2900 may further include a video display unit 2910 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 2900 also includes an alphanumeric input device 2912 (e.g., a keyboard), a cursor control device 2914 (e.g., a mouse), a drive unit 2916, a signal generation device 2918 (e.g., a speaker) and a network interface device 2920.

The drive unit 2916 includes a machine-readable medium 2922 on which is stored one or more sets of instructions (e.g., software 2924) embodying any one or more of the methodologies or functions described herein. The software 2924 may also reside, completely or at least partially, within the main memory 2904 and/or within the processor 2902 during execution thereof by the computer system 2900, the main memory 2904 and the processor 2902 also constituting machine-readable media.

The software 2924 may further be transmitted or received over a network 2926 via the network interface device 2920.

While the machine-readable medium 2922 is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present invention. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals.
